Maybe this is a dumb question, maybe it is not so please don't slaughter me if it is. The flies are out of control here this season, more so than I ever remember. We currently use a fly spray for our horses (not sure of the brand will have to check in the a.m.) and it seems to do NOTHING for them. Other than fly sheets does anyone have any type of remedies for these flying satans? I am all ears on this one!
